One call to C<getopts($optstring)> parses +all the options using the C<$optstring> as a list of simple switches +(letter) and switches with arguments (letter followed by C<:>). + +Option values are directly written into local variables of the form +C<$opt_S>, where C<S> is the switch name. + +An optional hash can be used as a second argument, with switches as keys +and subs as values. When a switch is met, the sub C<$foo> is called as +C<$foo> for a simple switch and as C<$foo(option_value)> for a switch +with argument. |
